Estuary and Sumner catchment

The Estuary and Sumner Flood Protection Programme includes Southshore, Redcliffs and parts of Sumner.

Flooding of the Estuary is driven by extreme tide events. The options for flood management being investigated include stopbanks, floodwalls, new pumpstations and new and repaired pipework to restore the stormwater and drainage network.  All options will have to consider long-term impacts and benefits.
